ENGINE Filed Jan. 18, 1928 2 Sheets-Sheet 2 I Ma@ INVENTOR WITNESS= ATTORNEY Patented Sept. 22, 1931 UNITED STATES PATENT OFFICE PAUL C'. MILLER, 0F LA 1411A, 'HONDURAS ENGDTE application and January 1s, 192s'. Serial No. 247,864.

m, vide a plurality of members or dividing the chamber into a number of compartments which receive the impelling fluid, with shoes on thel inner ends of the members engaging the oscillatory member, with yieldable means for keeping the shoes in engagement with the oscillatory member.

Another object of this invention is to subdividthe explosions of a large volume of gases into small impacts rapidly following ga each other, without the necessity of construction of a plurality of expensive and delicate parts, as indifidual cylinders, connecting rods, pistons and bearings.

A further` object is to reduce the local a5 stresses of high pressure by sub-dividing into small. individual compartments, which receivesaid pressure successively and thus permit reduction of the weight and material necessary to build up a high powered engine.

Another object is to provide a perfectly balanced engine whereby all eccentrically moving parts are counterpoised by similar parts of same weight, without resorting to ily wheels, counterweights or other devices which have otherwise no useful function.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view through the improved device the section being taken' on line 1-1 of Figure 2.

Figure 2 is a sectional view on line 2-2 of Figure 1, showing two units connected with the same shaft.

As shown in these views, 1 indicates a circular casing, through `the center of which passesthe shaft 2 to be driven, said shaft 55 eing )ournaled in the sides of the casing b means of the anti-friction bearings 3. ring-shaped partition 4 is arranged in the casi and an oscillatory member ,5 of circular s ape is eccentrically mounted in the chamber formed by the partition 4. A disk 6 is eccentrically'connected with the shaft 2 and ball bearings 7 are laced between the disk and the inner wall o the member 5. A wear ring 8 is fastened to the outer circum- 65 ference of the member 5 by being shrunken thereon or otherwise fastened thereto.

A lurality of telescopic partition forming' members 9 are slidably arranged in pacln'ng glands 10 arran ed in thepartition 4, shoes 70 11 being pivote to the inner ends of such members and such shoes engaging the plate 8. The outer arts 9 of the telescopicmembers have thelr outer ends bearing against the inner circumference of the casing 1 and 75 each telescopic member has each part thereof made hollow so as to receive spring means 9 which tend to hold the inner parts with the shoes pressed against the member 5. The side edges of the inner parts of the telescopic members fit in a fluid-tight manner in grooves 12 forme'd in the sides of thecasin These telescopic members, as will be seen, ivide the crescent-shaped chamber formed by the member 5 and partition 4 into a plurality of 85 separate compartments which receive the explosive mixture or other impelling fluid from the inlet manifold 13, the inlet ports 14 of which are controlled by the movement of the member 5, as the port 14 of each compartment 90 will not be opened until the member 5 is in such a position as to make said chamber its full size.

The member 5 and the casing are provided with the holes 15 through which a cooling 95 medium may pass.

' Figure 2 shows a compressor and engine connected together, the exhaust Orts 16 of the compressor being connected y the passages 17 with the inlet ports 14 of the engine. W

The exhaust manifold of the engine is shown at 18. With this arran ement, the first device can be used as a b ower or compressor and the explosions can occur in the second device.

As will be seen, the propelling force in each compartment acts on the member 5 to move it tangentially and this movement of member 5 tends to rotate the eccentric disk 6 which is connected with the shaft 2,`so that said shaft 2 is rotated.

Attention is called to the fact that the member 5 does not rotate, but has a substantially oscillatory movement in the chamber formed by the partition 4. In other Words, the top part of this member 5 remains at the top throughout the movement of said member. As the member uncovers the inlet ports 14, air or carbureted air, according to which form of ignition system is being used, flows into the compartments, the orts of which are uncovered, and then t is air is compressed by the further movement of the member 5. The compression increases as the size of the compartments is reduced by the movement of the member 5 until the member reaches a position Where the compartment A, for instance, in Figure 1 is reduced to its smallest extent. The tiring of the mixturein this chamber then takes place, which causes the member to move tangentially to the left in Figure 1, so that the chamber B is reduced to its smallest extent and then the firing of the mixture. in this chamber takes place, which causes the member to move to a position where the chamber C is reduced to its smallest extent and the charge in this chamber C tired. The explosions follow each other .in rapid succession and occur always at or nea-r the highest point of compression. When the carbureted air is drawn into the compartments, the device must be equipped with spark plugs, one for each compartment, but when a1r is drawn into the compartments, means must be provided for injecting fuel into the compartments after the air is fully compressed so that the heat of the compressed air will ignite the fuel. As both of these ignition systems are well known, it is vnot thought necessary to describe them in detail or illustrate them.

As the member 5 moves, the chambers opposite to those in which the charge is being ignited, Willbe of full size so that the inlet ports Will be opened and either air or carbureted air will be forced into such chambers and this flow of air Will force the burnt gases from the chambers, due to the fact that the exhaust ports are also open, as the exhaust ports are in alignment with the inlet ports. Then during the further movement of the member 5, both the inlet and exhaust ports will be closed and the air will be compressed, as before described. Thus the device Works on the two-cycle principle, with the member 5 acting as a common piston for all of the naanoo;

compartments. When two of the devices are coupled together, as in Figure 2, the right device acts as a compressor for the air, this air being held in the first device until the ports 14 are uncovered by the movement of the member 5 in the second device, and this air will rush into the compartments of the second device, expelling the burnt gases therefrom, and then t is air will be further compressed in the second device and iinally the charge will be ignited either by spark plugs or by fuel injected into the heated compressed air.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to be understood that may make changes in the construction and in 'the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
